Questions
How big is the IoT Environmental Monitoring Device Power PCB?
It measures 40 × 30 mm and has 4 copper layers, 1.6 mm thick.
What parts does the IoT Environmental Monitoring Device Power use?
42 parts, built around the MT3608, AXP2101, DW01A and S3B-PH-SM4-TB(LF)(SN). The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the IoT Environmental Monitoring Device Power KiCad files?
From the FredandFZ/Upwork_Benchmark repository on GitHub, at the commit this page was made from: the board is Datasets/project/43214420/deliverables/paid_18156583/IoT_Environmental_Monitoring_Device_Power/IoT_Environmental_Monitoring_Device_Power.kicad_pcb and its schematic Datasets/PII_clean_project/43214420/deliverables/paid_18156583/IoT_Environmental_Monitoring_Device_Power/IoT_Environmental_Monitoring_Device_Power.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the IoT Environmental Monitoring Device Power design in my own project?
Its repository states no licence, so its author keeps all rights: ask FredandFZ before reusing the design.
